RADIATOR FOR GAS HEATING BY INGANDESCENCE.

- Application filed April 22,

To all whom it may concern:

Be it known that I ANDRE GARBARINI, engineer, citizen o1. the Republicof France, residing in Oourbevoie, Seine, France, and whose post oliiceaddress is23 Rue de Colombes, have invented certain new and use fulImprovements in Radiators for Gas Heating by Incandescence; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification. p

This invention relates to improvements in the construction ofradiatorsfor gas heating by incandesce'nce making use of a gas mantle of the typeknown as inverted mantle, which is placed. in the horizontal position atthe focus of a parabolic mirror.

To provide for the proper working of such radiators, it is veryimportant that the man tle should be disposed onthe axis of the mirrorand maintained. in an elastic manner. For this purpose the claws of thering carrying the mantle are well. fitted upon plane surfaced lugsformed upon the steatite or porcelain burner and are held inan elasticmanner in this position by the pressure of a metal ring acted upon by aspiral spring.

The use of the ordinary inverted burners placed horizontally in heatingapparatus does not give quite the desired results as concerns theheating action, because the gas and air mixture rises tor the greaterportion to the upper part ofthe mantle which will be-' come overheatedwhile the lower parts are only slightly heated, thusshowing an irregularincandescence on the surface of the man tle. In order to obtain aregular incandescence upon the whole surface of the mantle, the latteris mounted upon a burner whose gas mixture outlet end is provided withholes at the upper part, whilst the lower part is bevelled, so as tocause the greater part of the gas mixture to proceed to the lower partsof the mantle, thereby producing the complete incandescence of themantle. Furthermore, the gas and air mixture should be properly adjustedin order .to provide for the emission'ot red orinttra-red rays whichgive the maximum calorific. eiliciency, and for this purpose the mantleis also construct= Specification of Letters Patent.

ed with meshes which are wide as well as thick.

Other improvements in the construction of these radiators will be set,forth hereunder.

' In the accompanying drawings:

Fig. 1 is a side view,'partly in section, or the whole radiator. f i

' Fig. 2 is a front view of the same.

Fig. 3 is a longitudinal-section on a larger scale shewin g the air andgassupplyingelement, the burner and the special mounting of the gasmantle.

v Figs. land 5 are also vertical sections on a larger scale of thejointed supporting base. Fig. 6 is an end view ofthe burner.

The radiator comprises a supporting base 1 whereon is pivoted at 2 anarm 3 which is secured to the parabolic reflector a. To the arm 3 issecured the nib 5 which serves to connect the flexible gas admissiontube, the gas passing through a cock 6 and proceeding thence to theregulating chamber through the small tube 7. The disposition of the nib5 adjacent the joint 2 of thereflector will produce only a slightmovement of the fiexible tube in all positionso'f the reflector 4.

On the axis of the reflector and'at the'rear of the latter is secured bymeans of screws a metal socket 8 wherein is engaged a tube 9 forming amixing chamber at one end whereof is secured the porcelain or steatiteburner 10. The tube 9. is fixed in position in the socket 8 by the setscrew 11, and it is provided outside the socket 8 with a screwthreadwhereon is engaged the ring'12- used to regulate the air inlet throughthe holes 13. When the adjustment has been once determined, the saidring is locked in position by a set screw 14L.

At the outer end of the tube 9 is situated the gas inlet tube 7 whichopens into a small chamber-15 having an orifice 16 for the admission ofthe gas into the mixing chamber 9. The amount of gas to be admitted intothis chamber 9 is regulated by means of a screw needle 17 which islocked in position by a set screw 18 after the regulating has beenperformed.

The gas mantle 19 which is made with wide and thick meshes, is mountedin the usual manner upon a steatite support '20 comprising threeattaching claws 21 adapted to engage in the rear of the In s 22 having aplane surface, against which t ey are held in an elastic manner and wellin the axis of the reflector by means of a cylindrical ring 23 actedupon by a spiral spring 24: disposed within the socket 8 and at theexterior of the mixing chamber 9.

The burner 10 which is screwed to the end of the mixing chamber 9 isprovided at the outer end and near the top with small holes 25 coveringabout half its surface, whilst thelower part 26 is out on a bevel so asto cause a considerable quantity of the mixture to proceed toward thelower part of theinantle whereby the same shall be made incandescentuponthe whole surface, which result would not be obtained were the mixtureobliged to flow'through holes distributed in anirregular' manner uponthe entire surface of the burner, as the mixture always tends to rise tothe upper part of the mantle. The latter; is preferably provided with asmallpiece ofplatinum or palladium sponge forthe automatic'ignition uponopening the gas inlet r The supporting base 1 of cast metalgfor exampleof aluminium is provided with two lugs 27, Figs. 4 and 5,which arerendered elastic by a saw cut 28 in the head. of the support. They areconnected by the pintle 2 whereon is pivotedthe arm 3 supportingthejrefle'ctor, which is preferably of cast aluminium. To obviategripping action, the snrfacesof the arm 3 engaging the lugs 27 are facedwith washers 29 of a different metal, brass for example,'wliich areinserted inthe same. i

The supporting base is also provided at the bottom' part with a hole 30whereby it may be'placed against the wall by engaging the-said 'holewitha suitable wall hook and is also provided with a hole 31 with gas tapfor ceiling suspension by screwing upon a suitable connecting member Thereflector d is provided at the front part with crossed protectors inflat metal which are hooked to the beaded rim of the reflector and aretwisted so as to afford but a "slight thickness in the direction of theheatrays.
